Mail, text, and in-person payment instructions
Pay by text
NBU's text program is primarily an outage and notification service, not a published text-to-pay enrollment. To enroll for outage notifications, text NBU to 830-629-4628; customers can report an electric outage with #OUT and check status with #Status. The number must be linked to the NBU account and standard carrier SMS rates may apply. NBU does not publish a water-bill pay-by-text keyword.
Mail-in address
New Braunfels Utilities, P.O. Box 310289, New Braunfels, TX 78131. Customers should include the bill stub/account number and allow sufficient time for receipt by the due date.
